The time compensating means provided by the present invention renders it uImecessary to take into consideration the cams or eccentric discs in respect to the degree of longitude, which effects great simplification in the storekeeping in respect to such dials or discs.

The supports 40 for the dials are so dis` Y lposed or relatively spaced that lthe monthindicating dial 46 can be mounted only in the position shown or in a position 180 degrees therefrom. This enables the dials tobe used for both the northern and southerny hemispheres, as in the northern hemisphere the scale47 would cooperate with the indicator 48 and in the southern hemisphere with the indicator 48.

Vhat I claim is l. A Y time switch control mechanism including in combination a member to be rotated in accordance with time, a month indieating scale thereon, an hour indicating scale supported thereby and movable relativeV thereto, a scale to indicate relative displacement of the .hour scale from its normal position and indicating the corrections made for local time, switch operating membersmov-` able relative to the hour scale, means for moving said members relative theretoin accordance with seasonal changes in the setting and rising of the sun(` 2. A time switch controlmechanism including incombination a member to be ,ro-V

tated in accordance withtime, a month indicating scale thereon, an hour indicating scale supported thereby and ,movable relative thereto, a scale to indicate relative dis-y placement oi' the hour scale from its normal position and indicating the corrections made for localV time, switch operating members movable relative to the hour scale, means for displacing said members from their normal n position to cause the switching operation to l Y be displaced a predetermined amount of time from normal'.
